Do you love your wife? Does she love you? if so then I think you would be better off going without then seeking the "services of a professional" (I love the way you put that) I know you will here around the swinging world that sex is just sex, and as one signature says, "whats love got to do with it anyway" (another saying I love). But what about the connection you get with being with someone you like. You wont get any better connection with a "Professional" then you would the lovely ladies of Playboy. At least masterbating to playboy wont destroy your marriage, or cause you to catch something icky.( that is the medical term for STD's).
If you need to seek out relations. I would suggest talking to your wife. See if you can't work things out there. I mean really talk, not a 5 minute thing bettween commercials. Like Alura says, try councelling.
If all else fails bring up that you have needs that need to be met. If she is unable to be there for you with this, can we talk about alternatives.
I know easier said then done. The people here are way more open minded then the average population.
But cheating my friend, is most definatly not the way to go.
As you can testify people in their 70's still like sex, so if you keep your eyes open, and check the swinger or alternative lifestyle sites you will likely find your match.
PLEASE, take care of things at home first.
Your friend,
Prettylady
